Abstract Fluid‐containing nanoparticle research is well‐known for its heat transmission properties due to real‐world applications in various thermal systems. This demonstration shows how time‐dependent magneto‐hydrodynamic (MHD) Brinkman‐type nanofluid can flow through a vertical oscillating absorbent plate immersed porous environment. The governing dimensional partial differential system of equations translated into non‐dimensional with applicable scaling variables. transient flow's momentum, and mass are solved using the finite semi‐discretization difference line method. obtained outcomes validated by comparing them previous works. Graphical resolutions heat, distribution fields presented examine essential physical terms isothermal ramped temperature impacts. It was found that magnifying Brinkman parameter magnetic brings decrement fluid velocity. In contrast, reversal deportment exposed an enlargement permeability parameters solute buoyancy effects. Reynold's number has shown declining impact velocity, but time progress unveiled contrary tendency. sprouting radiation deepens temperature, whereas rising absorption curtails temperature. concentration deflates growing Schmidt chemical reactive agent. wall friction increased porosity reverse trend parameters. Increasing Prandtl heat‐consumption helps raise gradient. gradient lessened on augmentation reaction number.
